I’m not sure.. but i don’t think the rendering engine on iOS is not designed to handle motion graphics inside the browser. Every time something changes in the page it needs to render the entire visible area and cache it as an image.

that’s not true because css 3d transforms are uber fast thx to hw acceleration
unfortunately, canvas is a whole different story.

I always feel Apple tries to portray that nothing except their OS based animations / transitions are smooth (to make users to feel nothing is excellent than their visual capabilities or the reason mentioned by flashedge). Weird but I guess may be their marketing aspects ties their engineers hands. We can expect such ugly behaviors from almost all the BIG and commercially successful companies. (We will see a lot similar games played by google; nothing good for developers and users)
